How to backup MySQL Database in command line with compression


For those who looking for way to backup mysql database,
you can use mysqldump to backup mysql database.

Below is the script example to backup mysql database in command line:-

$ mysqldump -h localhost -u username -p database_name > backup_db.sql

If your mysql database is very big, you might want to compress your sql file.
Just use the mysql backup command below and pipe the output to gzip,
then you will get the output as gzip file.

$ mysqldump -u username -h localhost -p database_name | gzip -9 > backup_db.sql.gz

If you want to extract the .gz file, use the command below:-

$ gunzip backup_db.sql.gz

    Thank you for the tip, much appreciated. I use to move big MySQL backups and sometimes you cannot handle those with phpmyadmin.

    Hi,

    Having installed xampp in my pc, I am ready to work on my various large database or dump files before I upload them to the live webhost/server.

    1. Now, how do I load a large database into the database created in phpmyadmin in xampp on my pc using mysql shell command??
    I have tried using phpmyadmin but was not successful due to exceeding the max limit.

    2. once it has been loaded successfully, then I can export or backup this same large database/dump again but this time, I want to backup into smaller parts (say there are total 30 tables and I want to backup into 3 x 10tables ) total 3 parts.
    How can I do this and what’s the shell command path or command strings to do such?

    Thank you in advance for any kind guidance and assistance.

    Regards,
    Chris

    Very good! I’ll use it in my backup script:

    #create (if not exist) backup folder
    mkdir -p /home/aus/project_bak
    cd /home/aus/project_bak

    # backup the project software
    tar cvf $(date +%Y-%0m-%0d_%0H%0M.CPP.bak.tar) /home/aus/Project

    # backup the web application
    tar cvf $(date +%Y-%0m-%0d_%0H%0M.WEB.bak.tar) /var/www

    # Thanks to Techie Corner, back up the database
    mysqldump -hlocalhost -uroot -proot users > $(date +%Y-%0m-%0d_%0H%0M.sql)
